why didn't they see there was water before it rolled into the water? >> reporter: the commanding general of the third infantry division saying, "this is a heartbreaking day. we are extremely saddened by the loss of three dogface soldiers, and injuries to three more. our hearts and prayers go out to all the families affected by this tragedy." >> investigators will look at a variety of potential causes. was it human error? did something on the machine break? we know that it occurred in the middle of the night, so was fatigue a factor at all? was weather a factor? all these will go into finding out why this happened and how to prevent it so it will never happen again. >> stephanie, you have an update on the three soldiers who survived? >> reporter: that's right. 2 of the 3 soldiers who were injured were treated at the army hospital here at ft. stewart and released. the third was transferred to another hospital and is expected to be okay. officials say they'll release the names of the solders that were killed after their families are notified. tom?

>> he was honestly surprised at the level of pushback. >> reporter: trump himself first proposed hosting foreign leaders at his doral resort. >> we have incredible conference rooms, incredible restaurants, it's, like, such a natural. >> reporter: trump promised to host the doral summit "at cost," but democrats did not take him at his word, quickly signaling their plans to investigate. foreign leaders and some republicans expressed reservations too. >> at the end of the day, you know, he still considers himself to be in the hospitality business. he wanted to put on a show. >> reporter: today, acting chief of staff mick mulvaney also sought to backpedal on another issue, admitting something the president has denied for weeks. >> there was no quid pro quo. there was no quid pro quo. there was no quid pro quo at all. >> reporter: on thursday, mulvaney admitted the administration did withhold military aid to ukraine in part to push ukraine to investigate democrats.

>> which ultimately flowed. >> but to be clear, what you just described is a quid pro quo. it is, funding will not flow unless the investigation is into the democrat server happens as well. >> we do that all the time with foreign policy. i recognize that maybe i didn't speak clearly on thursday, folks misinterpreted what i said. >> reporter: today, in his defense, mulvaney told fox news he never actually used the words "quid pro quo." >> i never said there was a quid pro quo, 'cause there isn't. >> reporter: this week, house impeachment investigators expect to hear from bill taylor, who was the top u.s. diplomat in ukraine. back in september, he sent a text message saying he thought it was crazy to withhold security assistance for help with a political campaign. taylor expected to testify tuesday. tom? >> david, thank you. we head overseas to syria,

where the clock is ticking on a 120-hour pause. kurdish troops have pulled out from one key town. but a kurdish commander tells abc news they will not clear the safe zone entirely. there are also fears about ethnic cleansing, and what the u.s. would do to stop it. abc news foreign correspondent james longman is in the region. >> reporter: with reports of pockets of fighting raging on, it seems to have been a pause that never was. but tonight kurdish forces have withdrawn from the key town of ras al-ayn, the first pullout since the conflict began. this move required as part of the deal the u.s. struck with turkey last week in which a safe zone would be carved out all along the border. president trump defending the deal. >> sometimes you have to go through some pain before you can get a good solution, but the kurds are very happy about it. [ speaking foreign language ] >> reporter: but kurdish commander nesrin abdulla says with more than 200 dead, they are far from happy. donald trump says the kurds are happy. [ speaking foreign language ] >> translator: i would tell mr. trump that the kurds are not

happy. they've killed all these people so of course we are not happy. this agreement has allowed turkey to occupy our land and kill our people. >> reporter: a major issue lies ahead. turkey is demanding kurdish forces leave the entire safe zone, something the kurds say they have not signed up for. but the rest of northern syria, that's not part of the agreement? [ speaking foreign language ] >> translator: exactly. this is not included. they only told us ras al-ayn. >> reporter: the kurds fearful turkey's ultimate motive is an ethnic cleansing sparked by president trump's removal of u.s. forces. >> for many, many, years, turkey had terrorists. they had a lot of people in there that they couldn't have. they've suffered a lot of loss of lives also. and they had to have it cleaned out. >> reporter: on "this week," secretary of state mike pompeo was pressed on the issue. >> can you assure the kurdish people and the president's allies in congress that you will not be party to ethnic cleansing? >> george, we were very clear and the vice president could not have been more clear when we

were speaking with president erdogan, in that turkish-controlled space, that there wouldn't be attacks on minorities. that this was about getting a cease-fire, a secure area, and that this, in fact, will save lives. >> james joining us live from northern iraq. house speaker nancy pelosi making a surprise trip to that region with a congressional delegation to meet with the king of jordan, and sending a public message about this crisis? >> reporter: that's right. pelosi leading a delegation of democrats and republicans to meet with the king of jordan. there's a real concern about a resurgent isis and for the kurds. and no doubt the visit was intended to send a message of congressional unity against president trump. >> james, thank you. and senator elizabeth warren was in iowa as a new front-runner threat to bernie sanders. but sanders is back in a big way, and with a key endorsement by his side.

>> reporter: sanders is trying to fend off a surging senator elizabeth warren, who had this to say about ocasio-cortez. >> i am a fan of the congresswoman. she's done some terrific work. we have worked together and i know that once this primary is over, we're all going to be on the same side.in studio. you've been tracking all the news from the democrats. and hillary clinton raising some eyebrows this weekend with what she said about how the russians may interfere in the election. let's take a listen. >> i think they have their eye on somebody who is currently in the democratic primary. and are grooming her to be the third-party candidate. she's a favorite of the russians. >> a clinton aide saying she was signaling tulsi gabbard. gabbard firing back, and challenging her to join the race.

some of the democratic candidates saying the comments go too far. >> yes, cory booker stressing the importance of unity in the party. and beto o'rourke saying tulsi gabbard is not being groomed by anyone. there is no evidence to support clinton's claims. and tonight, clinton's team did not return our request for comments. >> rachel, thank you. and now to a story in texas with a young father fatally shot inside his home. police say he was protecting his family from armed intruders. tonight, the chilling 911 call, and the surveillance footage authorities hope will lead to an arrest. here's marci gonzalez. >> reporter: tonight, detectives in texas searching for the home invaders who inexplicably killed this young father as he tried to defend his family. >> someone just bre y sbd. hr h young children up early thursday morning. he confronts two men. and within moments is shot in the chest. >> the person that shot your

possession of a firearm in public and was sentenced to three years of probation. the students immediately called coach lowe a hero. and portland police have praised him as well, saying it was a best case scenario. >> trevor, thank you. and still ahead on "world news tonight," how officials took the cranes down at the collapsed hotel site in new orleans. and the new images from behind bars. the hollywood actress spotted in a prison uniform. and the deadly spike in violence in chile. what is setting it off. the latest casualties from those riots. stay with us. the latest casualties from those riots. stay with us. or prescribed bril. it's for people who have been hospitalized for a heart attack. brilinta is taken with a low-dose aspirin. no more than 100 milligrams as it affects how well brilinta works. brilinta helps keep platelets from sticking together and forming a clot. in a clinical study, brilinta worked better than plavix.
